METHOD OF MAKING PAPVE'R BAGS. I

SPECIFICATION forming part of Letters Patent :No. 287,753, dated October 30, 1883.-

Application filed September 14, 1882. (No model.) i

To aZZ whom, it may concern:

Be it known that I, GEORGE O. BLOWERS,

of Oanajoharie, in the county of Montgomery and State of New York, have invented a new and useful Method of Making Paper Bags and I do hereby declare that the following is afull,

.clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application. 1

My invention relates to a method or process of making satchel-bottom paper bags, which will be hereinafter more fully set forth, and particularly pointed out in the claim of this application.

The paper bag which my new method has been invented to produce forms the subject'- matter of a separate application filed July 12, 1883, but will be shown in the drawings and described in the specification of this case, so.

that a better understanding may be hadof the improvement which is sought to be covered by the present application.

In the accompanying drawings, Figure 1 is 'and to this view I have added transverse'dotted lines and longitudinal heavy black lines, to indicate, respectively, where the subsequent cross-folding and the longitudinal pasting are to be done. Fig. 3 is a side view of a completed bag slightly distended, and Fig. 4 is a" perspective view, enlarged scale, of the lower portion only of the bag fully distended.

In the several figures the same part will be found designated by the same letter of reference.

- The blank A, from which to make the bag, is of a length twice that of the bag to be produced therefrom plus the width of the bag bottom, and of a width nearly equal to twice the width of one of the broader and plain sides of the intended bag. Said blank is first folded inwardly along the dotted lines a a and a a, Fig. 1, into the flattened tubular condition seen at Fig. 2, and is subsequently folded transversely, to form the bellows-like bottom folding, the blanks may be preliminarily,

creased at some or all of the lines where folding is to be done. 7

A blank longitudinally folded and supplied with paste (and then preferably transversely transformed into a complete bag, such as seen at Fig. 3, with bellows sides and bellows bottom, which, when distended, present a square or quadrangular bottom, as best seen at Fig. 4, by simply folding the blank transversely on itself at the transverse line's dotted in at Fig. 2. a plan view or diagram showing the shape of In making the bellows bottom at the lines 0 d e, the portions B and G are brought face to face, with their paste-lines coinciding, the folded blank being properly compressed by.

any suitable means, to keep the freshly-pasted parts in contact, and to'finally flatten or break down the material along the folds. In thus folding and pasting the blank to complete the bag, the pasted portions of the blank lying between the lines d and e are brought in contact with the paste-line's of part B from c to f, and the pasted portions lying between the lines (I and c are brought in contact with the pastelines of. part 0 from c to 9, while the pasted creased, as shown in Fig. 2) may be readily portions of B and 0 from the points f and g to the extremities of the-blank, respectively, nearest to said points are also brought (face to face) together.

In making the bellows-fold to form the bottom of the bag, the order of making the cross- 4 folds may of course be varied without departing from the spirit of my invention with reference to the novel method herein described.

The folding over of the sides of the blank along the lines a a, and the subsequent pasting and cross-folding, as described, will produce, it will be seen, a bag which not only has a paper bags, consisting, essentially, in folding over the longer edges of the blank, as at a a and a a, applying paste to the folded-over edges, and then further folding the folded and pasted blank transversely at the lines 0, d, and e, and so as to bring together 'the portions B and 0, all as specified.

In witness whereof I have hereunto set my hand this 10th day of September, 1883.

GEORGE O. BLOVVERS. In presence of J AMES ARKIN, HIRAM L. HUsToN.
